1 '0 all whom it may concern:

Be it known that I, FRANK Mossnnns, a citizen of the'United States,residing at httleb-oro, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements, inBeam Heads, of which the following is a specification.

This invention relates to improvements in the constructing of loom beamheads and the like of sheet metal, and in the method of forming thesame, and the object of thls invention is to provide such a head with afriction drum or sheave which is also formed from sheet stock andsecured tothe outer face of the head-plate by a welding operation thusproviding a head of this character wit-h the maximum strength, theminimum weight and the minimum cost of construction.

v appended claims.

In the accompanying drawings:

Figure 1 is a face view of a loom-beam head of my improved construction.

Figure 2 is a central sectional elevation .through the head.

Figure 8 is a perspective View showing a strip of sheet stock from whicha fI'lCtlOIl drum or sheave is formed.

Figure 1 shows this strip of sheet stock as rolled into ring form withits ends abutting and welded together, one edge of the ring being thenrolled or turned up to form a flange on the ring, the unturned edge ofthe-ring being secured to theouter face of the head-plate by a weldingoperation.

Figure 5 is a modification of the construction of beam head illustratedin Figure 2, showing a different style of central hub welded to theouter face of the head-plate.

I have herein shown and described a construction of beam-head which maybe employed for loom beams, spools or other similar articles ofmanufacture, which head members are formed essentially of a disc havinga grooved or channeled member secured to its outer face the same beingof a diameter less than that of the face plate thereby providing asheave or friction drum for the purpose of receiving a friction band orbelt to which a tension weight or other tension means may be applied forthe purpose of controlling the rotation of the beam as the yarn or warpis drawn from the body portion thereof, and the following is a detaileddescription of one method by which the same may be constructed 2- -Withreference to the drawings, 10 designates the headmember which may beconstructed of any suitable material but which is preferably cut fromsheet stock such as steel or the like, into disc form. In order tostiffen the outer edge of this disc I roll its periphery outwardly as at11 thus formmg a coiled or rounded flange.

In this particular construction of loom beam-head it is desired to formthe annular groove or channel member 12 of a diameter less than that-ofthe plate or disc and'to accomplish this in a simple and effective way Icut a strip of sheet stock 13 as illustrated in Figure 3, bend the sameint-o ring shape as illustrated in Figure 4, welding together as at 1%their abutting edges. I then roll or turn up the outer edge of this ringto form a flange as at 15 and finally secure the unrolled edge 16 to theouter face of the head-plate by a welding operation which operation isrendered possible by the forming of both the headplate and the sheave ofthin sheet stock of a character that adapts itself to a weldingoperation.

By this construction it will be seen that no rivets are required tofasten the sheave to the face of the plate as rivets in such a case arequite undesirable as when they pass through to the inner face of thehead-plate they are apt to work loose and catch and injure the yarn.Therefore by this construction of welding the edge of the friction ringor sheave to the outer face of the plate, the inner face of the plate isleft entirely smooth and finished thus doing away with any innerfastenings which the yarn can possibly engage.

In loom beam-heads of this character it is found desirable to providesome means which may be engaged by a driving member for rotating thebeam with its sheave and to accomplish this in a simple and effectiveway I have provided a lug or small plate 17 cut from sheet stock withits outer edge Welded to the inner surface of the sheave member and itsside edges welded to the outer face of the head-plate. In this waysupported in its position by means of a reinforcing center face plate 20which engages it and which is preferably secured in position by aWelding operation, its central portion being offset outwardly from theplane of the head-plate to extend over a spacing collar 21 whereby thecentral hub is firmly supported in its position.

In some other cases 1 provide a central hub 22 as illustrated in Figure5, the inner edge of which is welded to the outer face of the headplaterBy my improved method of forming a loom beam-head having a friction drumor sheave of sheet stock the sheave member being of less diameter thanthat of the head plate and secured to its outer face by a weldingprocess, I am enabled to form such a head of the maximum strength andminimum weight at the minimum expense and in addition to theseadvantages over the old style heads of this character, I am enabled tomeet all the requirements of the heavier and more expensiveconstructions.

Having thus described one illustrative embodiment of my invention andthe best mode known to me for carrying out my method, I desire it to beunderstood that although specific terms are employed, they; are used ina generic and descriptive sense v; and not for the purpose oflimitation, the

scopeof the invention being defined and limited only by the terms of theappended claims.

I claim: 1. A method of forming a loom beanr I head or the like of sheetmetal, which consists in providing a main head-plate, punching a holethrough its center, forming a bar 2. A method of forming a loom beamheador the like of sheet metal, which C011? sists in providing a main head,punching a hole through its center, securing a central hub thereto,forming a bar or strip of steel into a ring of a diameter less than thatof the head-plate, welding together the ends thereof, rolling one edgeof the ring outwardly forming a retaining flange, welding the unrollededge of the ring to the face of the plate concentric to the center hole.

3. A method of forming a loom beam-head or the like of sheet metal.which consists in providing a main head-plate, punching a hole throughits center, attaching a hub about said center hole, forming a bar orstrip of steel into a ring of a diameter less than that of theheadplate, welding together the ends thereof, welding the edge of thering to the face of the plate concentric to the center hole, welding aradial driving lug to the face of the main plate at a point intermediatethe inner surface of the ring and said hub.

4. In a loom beam-head or the like, a head member comprising a metaldisc having its peripheral edge rolled outwardly t stiffen the same, anda friction drum or sheave member constructed of sheet metal in ring formof a diameter less than that of said disc and having one edge turned outwardly with its unturned edge welded to the outer face of said disc, anda central hub' secured to the outer face of said disc.

5. A. method of forming a loom beamhead or the like of sheet metal,which consists in providing a main head-plate, punching a hole throughits center, forming a ring of a diameter less than that of theheadplate, and welding the edge of the ring to the face of the plateconcentric to the center hole whereby the inner working surface .of thehead-plate is left smooth and intact.

In testimony whereof I aflix my signature.

FRANK MOSSBERG.
